[Articulation disorders in aphasia. Considerations in several clinical cases]

Selective deficit of verbal output not associated to other anomalies of language, represents a syndrome in which articulatory as well as linguistic aspects can be independently affected. The critical lesion for pure articulatory deficit appears to involve left prerolandic cortico-subcortical structures. Nevertheless, in relation to individual differences in cerebral organization, damage in these structures can be responsible for a simultaneous deficit of articulatory and linguistic mechanisms.
